While I like the double-walled idea, the amount of liquid this cup holds is significantly less than I anticipated. In addition, the silicone top off gases, initially, so I have given up using it for now. Hoping in a few more weeks, it will not smell so bad!

Not a bad item. The first two arrived broken but exchanged free of charge. Handy for morning coffee without spills(especially when going up stairs). The lid stays tight, but has a "rubbery" smell to it.
